密着性、耐侯性に優れた塗装を施すことが難しかった。BACKGROUND OF THE INVENTION The above-mentioned inorganic board is used as an incombustible building board for interior boards, exterior boards, roofing materials and the like. The surface of such an inorganic plate is coated to reinforce and protect it. A water-based paint is recommended as the paint used for painting the above-mentioned inorganic plate. What is important is that the water-based paint uses a synthetic resin emulsion as a vehicle. In the synthetic resin emulsion, the molecular weight of the synthetic resin can be increased to improve weather resistance and durability. It is suitable for painting building boards exposed to the outside. In addition, the specific gravity of the roof material is generally 1.8.
It has a high specific gravity of ~ 2.2, and there is a demand for lightweight roofing materials from the structural problems of the load on buildings and the working environment of construction workers. However, it has been difficult to apply a coating having excellent adhesion and weather resistance to a lightweight roofing material having a specific gravity of 1.5 or less.

めて深刻なものとなる。However, the synthetic resin emulsion, which is the vehicle of the water-based paint, is a dispersion of synthetic resin particles with a large particle size, and when coated on the surface of the inorganic plate, the paint penetrates into the inorganic plate. However, there is a problem that the formed coating film has poor adhesion. In particular, in the case of a lightweight and good workability inorganic plate having a low specific gravity, since the density of the inorganic plate is low and the internal structural strength is small, in a water-based paint that is difficult to penetrate into the inorganic plate, the formed coating film is the inorganic material. It becomes easy to peel off together with the surface layer of the plate, and the problem of adhesion becomes extremely serious.

In order to improve the ultraviolet resistance of the paint, it is desirable to add the pigment or filler to the synthetic resin emulsion. As the synthetic resin emulsion, synthetic resin emulsions usually used as paint vehicles such as acrylic resin emulsion, vinyl acetate resin emulsion, styrene resin emulsion, urethane resin emulsion, and styrene-butadiene copolymer emulsion are used, but they are resistant to alkali and weather.

% By weight, 12-16% by weight of the pigment or filler, preferably 13.5-14.5% by weight, 65-75% by weight of water, preferably 67.5-70% by weight. When a water-based paint is applied to the top coat, a synthetic resin having a low molecular weight and slightly inferior weather resistance may be used as the undercoat water-based paint before the medium-type solvent-based paint is applied.

す。In the present invention, the solvent-based paint is applied to the surface of the inorganic plate prior to the coating with the water-based paint. In the solvent-based paint, since the synthetic resin is dissolved in an organic solvent at a molecular level, when the solvent-based paint is applied, the solvent-based paint permeates from the surface of the inorganic plate to the inside, and The internal structure in the vicinity is reinforced, and due to such anchoring effect and internal structure reinforcing effect, the coating film firmly adheres to the surface of the inorganic plate. When a water-based paint is applied as the undercoat, there are gaps formed between the synthetic resin particles in the coating film formed by the water-based paint. Penetrates into the inorganic plate through the gaps in the paint film. Therefore, the internal structure near the surface of the inorganic plate is reinforced, and the coating film of the solvent-based paint is anchored through the gaps of the coating film of the water-based paint, so that the coating film of the water-based paint is applied to the surface of the inorganic plate. Fixed to. In particular, the roofing material as a base material has a high specific gravity to increase strength, and improves the adhesion and weather resistance of the coating film.However, even if the base material has a low specific gravity, a solvent-based paint is used in the coating method of the present invention. By coating prior to the water-based paint, the adhesion and weather resistance are improved by the above-mentioned action. When a water-based paint is applied onto the coating film in a state where the solvent-based paint thus formed is dried, good adhesion is exhibited between the coating film of the solvent-based paint and the coating film of the water-based paint. .
